Deferred slanted-edge analysis: A unified approach to Spatial Frequency Response measurement on distorted images and Colour Filter Array subsets

Author: Van den Bergh, Frans Date: Mar 2018 The slanted-edge method of spatial frequency response (SFR) measurement is usually applied to grayscale images under the assumption that any distortion of the expected straight edge is negligible. By decoupling the edge orientation and position ... Read more
Defining the South African acute respiratory infectious disease season

Author: Motlogeloa, O ; Fitchett, JM ; Sweijd, Neville A Date: Jan 2023 The acute respiratory infectious disease season, or colloquially the “flu season”, is defined as the annually recurring period characterized by the prevalence of an outbreak of acute respiratory infectious diseases. It has been widely agreed ... Read more
Efficacy of a plant-produced clade 2.3.4.4 H5 influenza virus-like particle vaccine in layer hens

Author: Abolnik, C ; O'Kennedy, Martha M ; Murphy, MA ; Wandrag, DBR Date: Jun 2022 Outbreaks caused by Goose/Guangdong H5 highly pathogenic avian influenza (HPAI)-lineage viruses continue to occur in unprecedented numbers throughout Eurasia, the Middle East and Africa, causing billions of dollars in economic losses and the ...

Exploring functional dynamics of innovation for inclusive development: Event history analysis of an ICT4D project

Author: Maarsingh, B ; Grobbelaar, SS ; Uriona-Maldonado, M ; Herselman, Martha E Date: Aug 2021 Information and Communication Technologies for Development (ICT4D) projects aim to improve the living conditions of marginalized communities. However, ICT4D interventions have high failure rates. We draw on the Technological Innovation for ... Read more
In living colour – South African aquatic scientists make a splash in biodiversity campaign

Author: Lain, Elisabeth J ; Smith, Marie E Date: Jan 2024 A new age of satellite remote sensing is upon us. High-tech sensors capable of imaging the earth at over 100 spectral wavebands are now a reality. These sensors, known as hyperspectral radiometers, capture very fine spectral features of the ...

Land use induced land cover changes and future scenarios in extent of Miombo woodland and Dambo ecosystems in the Copperbelt province of Zambia

Author: Malunga, MM ; Cho, Moses A ; Chirwa, PW ; Yerokun, OA Date: Aug 2021 The pattern of Miombo woodland conversion to other land uses and the attendant impacts on vital Miombo ecosystems such as dambos is not well understood. Using the Copperbelt province of Zambia as a case study, we assessed the spatio-temporal ... Read more
Multi-threaded compression of Earth observation time-series data

Author: Swanepoel, Derick ; Van den Bergh, Frans Date: Mar 2017 Earth observation data are typically compressed using general-purpose single-threaded compression algorithms that operate at a fraction of the bandwidth of modern storage and processing systems. We present evidence that recently developed ... Read more
Potential opportunities to convert waste to bio-based chemicals at an industrial scale in South Africa

Author: Mandree, PM ; Thopil, GA ; Ramchuran, Santosh O Date: Oct 2023 Globally, greater than 30% of waste is disposed of in some form of landfill, and it is estimated that annual waste-related emissions will increase by up to 76% by 2050. Emissions arising from fossil fuel-derived products and waste disposal ... Read more
Robust edge spread function construction methods to counter poor sample spacing uniformity in the slanted-edge method

Author: Van den Bergh, Frans Date: Jun 2019 The slanted-edge method describes an algorithm for measuring the spatial frequency response (SFR) of digital imaging systems. The method can be applied to edges oriented at nearly any angle, but there are some angles that cause simplistic ... Read more
Sustainable co-management of acid mine drainage with struvite synthesis effluent: Pragmatic synergies in circular economy

Author: Masindi, Vhahangwele ; Mbhele, Nkhangweleni R ; Foteinis, Spyros Date: Apr 2023 Herein, the alkaline supernatant of a struvite recovery system from municipal wastewater was successfully co-managed with acid mine drainage (AMD). Various ratios (v/v) of AMD to struvite supernatant were examined, and the quality of the ... Read more
Systems dynamics approach for modelling South Africa’s response to COVID-19: A “what if” scenario

Author: Mutanga, Shingirirai S ; Ngungu, M ; Tshililo, FP ; Kaggwa, M Date: Feb 2021 Background: Many countries in the world are still struggling to control COVID-19 pandemic. As of April 28, 2020, South Africa reported the highest number of COVID-19 cases in Sub- Sahara Africa. The country took aggressive steps to control ... Read more
Understanding diarrhoeal diseases in response to climate variability and drought in Cape Town, South Africa: A mixed methods approach

Author: Lee, TT ; Dalvie, MA ; Röösli, MS ; Merten, S ; Kwiatkowski, M ; Sweijd, Neville A ; Cissé, G ; Mahomed, H Date: Aug 2023 Background: The climate of southern Africa is expected to become hotter and drier with more frequent severe droughts and the incidence of diarrhoea to increase. From 2015 to 2018, Cape Town, South Africa, experienced a severe drought which ... Read more
